Why Won't My Garage Door Open? 7 Most Common Causes
Garage door not opening? Here are the 7 most common reasons — broken springs, dead remotes, misaligned sensors — and how an Angier, NC tech diagnoses each.
Why won't my garage door open?
If your garage door refuses to open, the cause is almost always one of seven things: a broken torsion spring, dead opener motor capacitor, misaligned safety sensors, a snapped lift cable, a tripped GFCI outlet, dead remote batteries, or the manual lock being engaged.
The fastest way to diagnose: pull the red emergency release rope. If the door is now extremely heavy (150–250 lbs) and won't stay halfway open on its own, your spring is broken — this is the #1 cause we see in Angier, NC. If the door lifts easily by hand but the opener motor just hums or clicks, the issue is electrical (capacitor or logic board).
Misaligned sensors will let the door close but never open via the wall button — instead, the opener light will blink 10 times. Realigning the two photo-eye sensors at the bottom of the tracks is a 5-minute fix.
Never try to replace a torsion spring yourself. They store enough energy to cause serious injury. Email office@angiergaragedoorrepair.com for same-day service in Angier, NC and surrounding Harnett County.
Key takeaways
- Broken torsion spring is the #1 cause (look for a 2-inch gap in the spring above the door)
- Hum-but-no-movement usually means a $30 capacitor — not a new opener
- Blinking opener light = sensor misalignment, fixable in minutes
- Always pull the emergency release before forcing the door
